Abstract
A low profile positive displacement pump system is disclosed. The pump system includes a gasoline powered engine with a vertically disposed crank shaft. The system also includes a piston pump with at least one horizontally disposed piston, and a pump shaft assembly which mounts onto the crank shaft. A base including a cavity for retaining the pump is provided. The engine mounts directly onto the base, and fixes the orientation of the pump shaft assembly with respect to a driven end of each piston. The pump shaft assembly includes at least one eccentric camming surface for contacting a driven end of the piston and for causing each piston to complete one stroke per revolution of shaft rotation. A high pressure piston pump base is disclosed, comprising a main body including an upper surface, wherein the upper surface is suitable for mounting directly to a mounting flange of a gasoline powered engine having a vertically disposed drive shaft. A central cavity is provided which is of a size and shape suitable for retaining a high pressure pump. The cavity is of a size suitable for holding the pump stationary during operation. A high pressure, low profile twin piston pump suitable for bei…
